IMPROVEMENT IN FlRE-PLACEQ OR FRANKLIN STOVESr Specification formingpart of Letters Patent N 0. 127,265, dated May 28, 1872.

I, JOSEPH PEGKOVER, of the city of Cincinnati, in the county of Hamiltonand State of Ohio, have invented. certain new and useful Improvements inOpen Stoves, of which the following is a specification:

My invention, including several minor improvements of generalapplication, consists particularly in such a combination ofair-chambers, channels, and reservoirs as will best conduct a continuouscurrent of warm air up through a perforated top on the stove.

In the accompanying drawing consisting of two plates, and forming partof this specification, Figure I is a front view of my stove, showing theperforated top. Fig. II is a slatted blower. Fig; III is a rear view, inperspective, of the stove with the perforated top reversed and part ofthe back broken out to show the course of the air-currents. Fig. IV is acentral vertical horizontal section of the stove. Fig. V is alongitudinal cross-section of the same through the plane indicated bylines X X of Fig. IV.

A is the removable perforated top. B is an inclined brick fire-plate,forming, with the upright fire-back E, an angle corresponding to theangle described between the inclined bottom bars of the grate-basket andthe upright fire-back E. O O are the angular side plates of thefireplace, forming, with the inclined top plate, a complete combinationof reflectors. F is a cast-iron tuyere located between the inclinedplate B and the fire-back E. G is a revolving tri'vet with its standardinserted into perforated lugs on the upper grate-bars, being thusattached to the grate in a simple, cheap, and durable manner. H H areair-chambers in the backs of the stove, which conduct air into thereservoir I, inclosed between the angular plate B, the back of thegrate, and an adjustable top plate, J. This plate J is constructed withtwo parallel flanges, forming a recess into which the top of plate Bfits closely, so as to exclude the smoke from the reservoir I. K is anair-chamber at the rear of the stove, communicating by a channel withthe recess under the grate-bars, from whence it receives air andsupplies it to the tuyere F. L L are openings in the base of the stovethrough which the air is conducted into the recess M contained betweenthe angular side plates 0 G and the exterior sides of the stove. N is aremovable panel in the rear of the stove, containing the airchamber K,and is removable for the purpose of repairing the linings of the grate.Fig. II represents a slatted blower, the slats a, of which are eitherlongitudinal or vertical, and may be turned to regulate the draught, butare prevented from turning entirely round by the stops b b. O is a platenear the top of the grate, which covers completely the fire-place, andshuts off all communication between it and the perforated top A.

The current of hot air is created in the following manner: The cold airpasses up through the channels H H into the reservoir I, where it isheated by coming into direct contact with the hot plate B, which isdirectly over the fire. The heated air then passes out through orificesin the sides of the reservoir, Fig. III, into the recesses M, whence itascends and passes out through the perforated top A. Clo-operating withthis current of air is another current coming up through the openings Lin the base of the grate into the recesses M, where, in its ascendingcontact with the heated side plates 0 O of the grate, it becomes heatedand rises through the top A. Thus the entire surface in contact with thefire is surrounded by an ascending current of cold air, which, in itsascent, absorbs the heat and conveys it into the room. The tuyere F,communicating with the air-chamber and the fire-place, is used toconduct hot air to mingle with the products of combustion while they areintensely heated in the fire-place, which greatly facilitates theircombustion. If unconsumed, these gases pass off as volatile carbon orsmoke.

What I claim as new, and desire to secure by Letters Patent, is

'1. A grate-with the upper front bars perforated to hold a trivet,substantially as described.

2. The combination of the inclined bottom bars, the vertical fire-back,the inclined fireback, and the angular sides O 0, all bounded by rightlines, substantially as described.

3. The air-passages H, in combination with the reservoir I, the recessesM extending fromthe bottom of the stove to the top of the smokeflueplate, and the perforated top A, substantially as and for the purposesspecified.

4. The triangular reservoir I formed by the 7. The loose panel back,containing the airinclined fire-brick plate B, top J, and verticalchamber K and air-tubes H H, substantially back, and provided withinduction-fines H H as shown. in the back, and eduction-fines I I at theends J OSEPH PEGKOVER. of said reservoir, for the purposes specified.
